Daily money market rate averages tracked across our database of 8,500+ banks and credit unions, updated every evening.
South Carolina high-yield MMA rates rose 0.023 points over the past 7 days to 3.060% APY.

South Carolina Money Market Rate Forecast, Next 12 Months
Money market rates move with Federal Reserve policy. Our model uses the current SC high-yield MMA average and a Fed funds spread to project the likely rate trajectory for 2026–2027.
Money market account rates are variable and move in close correlation with the Federal Reserve’s federal funds rate target. Our 12-month forecast is derived from the current SC high-yield money market average of 3.060% APY and a Fed funds spread model calibrated to the historical relationship between policy rate changes and deposit rate adjustments at banks and credit unions.
Key assumptions: the Federal Reserve holds the federal funds rate at its current level over the next 12 months, with the possibility of one 25 basis point increase; deposit rates at banks and credit unions track policy-rate changes within 60–90 days. High-yield money market rates tend to adjust faster than standard branch-based accounts.
Important notice: This forecast is for informational purposes only and should not be used as the sole basis for financial decisions. Rate forecasts carry significant uncertainty. The actual trajectory will depend on Federal Reserve decisions, economic conditions, and competitive dynamics among financial institutions in South Carolina.

How to Find the Best Money Market Rates in South Carolina
What to compare when shopping for a money market account in South Carolina
To find the best money market APYs in South Carolina, start with credit unions and online-only banks: South Carolina has 23 credit unions in our database, and they consistently offer some of the highest yields because they are member-owned nonprofits with lower overhead than traditional banks.
Always compare the APY (Annual Percentage Yield), not just the interest rate, and pay close attention to balance tiers. Many money market accounts only pay their advertised top rate above a minimum balance of $1,000–$25,000, with lower rates (or monthly fees) below that threshold. The current SC high-yield money market average is 3.060% but top local institutions are offering as high as 4.07%, so shopping around pays off.
Unlike a CD, money market rates are variable. Your rate can change at any time with Federal Reserve policy. Also check check-writing and debit card limits: most MMAs allow a set number of withdrawals per month, and exceeding the limit can trigger fees. Review your account periodically to ensure your APY remains competitive.
When a Money Market Account Makes Sense
- Emergency fund with flexibility: You get savings-level yields plus limited check-writing and debit access. South Carolina high-yield money market rates currently average 3.060% APY, far above a typical checking account.
- Larger balances ($10,000+): Many MMAs pay tiered rates that rise with your balance, so bigger deposits often earn more than they would in a standard savings account.
- Parking cash between investments: A high-yield money market account at South Carolina institutions keeps idle cash working harder while remaining fully accessible.
- You prefer banking locally: 31 institutions in South Carolina report money market rates to our database.
- You’re among South Carolina’s 18.9% of residents aged 65+ for whom liquid, accessible savings complement fixed-income holdings.
- No rate lock-in risk: Unlike a CD, your rate moves up with the market if rates rise further.
Consider an Alternative If…
- You want a locked-in, guaranteed return → South Carolina CD rates
- You don’t need check writing and want a lower minimum → South Carolina savings rates
- You need daily transaction access → South Carolina checking rates
